IMPROVEMENT IN AXLE-BOXES FOR CARRIAGES.

Specification forming part of Letters Patent No. 95,543. dated January4, 1870.

T 0 all whom it may concern.-

Be it known that we, ANSEL GRANVILLE BAKER and GEORGE MORRIS ENNIS, ofNew Bedford, of the county of Bristol, of the State of Massachusetts,have made a new and useful Invention or Improvement Having Reference tothe Axle-Boxes ofOarriages; and we do hereby declare the same to befully described in the following specification and represented in theaccompanying drawings, of which Figure 1 is a side elevation, and Fig. 2a longitudinal section, and Fig. 3 a transverse section, of acarriageaxle journal and its box as provided with our invention.

The box is bushed with a soft metal, or a composition of soft metals,generally known to mechanics as Babbitt metal.

For the purpose of holding the bushing in pace we construct the box with.two recesses or shoulders, one being at each of its opposite ends, andalso with recesses at its middle, the latter recesses being to preventthe bushing from revolving within the box and the former ones being toprevent it from moving endwise therein.

In the drawings, A denotes the box, or sleeve, as it is usually termed,it being made of cast-iron or other hard metal.

The shoulders or recesses in the box are shown at a b and c d, theBabbitt metal bushing being exhibited at B.

In casting the bushing into the box and about the journal 0 whentherein, the said bushing, at its ends, is to extend into the recessesof the box or against the shoulders at b in manner as shown at c d inFig. 2, and,

furthermore, the bushing is to extend into the recesses 01 d in manneras shown at e in Figs. 2 and The above method of constructing the boxand forming the bushing will cause the latter when cast into the box andabout the journal to be securely fixed in the box so as not only to beprevented from moving endwise therein, but of being revolved in andrelatively to it.

We make no claim to anything, combination, or arrangement of parts asrepresented in either of the Patents Nos. 62,126, 62,356,. and 74,029,as our box, although being similar in some respects to those describedin such patents-that is, as having a metallic lining cast or otherwisefixed in it-difiers in others,

particularly in the arrangement of the lining and itssupporting-cavities. Our lining goes from one shoulder to the other andbeyond the two, and extends up into recesses arranged beyond the twoshoulders, which is not the case with either of the linings of the boxesshown in such patents. Furthermore, our lining is cast into intermediaterecesses, 61 d, which prevent it from turning around in the box.

By so arranging the shoulders a b and recesses c d no part of the metalof the box is projected against the bearing-surface of the axle to wearor cut the same or be worn thereby.

We save by our improvement the process of subjecting the box to an acidsolution, and next tinning its inner surface preparatory to casting themetal into it, such process being described in Patent No. 74,029,hereinbefore referred to.

We claim, therefore- In the soft-metal-lined box, the lining, asextended into recesses d d and beyond the shoulders to b, and into therecesses or grooves c d, arranged in the sleeve A, as set forth.
